The technical solution of the utility model is as follows: a kind of Whole frequency band antenna structure of mobile phole, and it includes metal shell on the back and is located at Circuit board below described metal shell on the back, it is characterised in that described metal shell on the back has the center of ground connection and as aerial radiation The Department of Radiation of body, described center has main part and the side extended respectively, described Department of Radiation from described main part two lateral buckling Described center one end and and described center between leave the gap of an insulation filling, the two ends of described Department of Radiation respectively with institute State the end of side relatively and to be spaced and arrange the breaking joint forming insulation filling, described circuit board near the side of described Department of Radiation with Described center edge is concordant so that form clearance zone between described circuit board and described Department of Radiation;

This antenna structure of mobile phole also includes distributing point, at least one earth point and the tuning electricity being located on described Department of Radiation Road, described distributing point is arranged near wherein breaking joint described in, and described earth point includes apart from nearer first the connecing of described distributing point Place and apart from described distributing point the second earth point farther out.

Preferably, described first earth point and described second earth point are respectively positioned on described distributing point the same side.

Preferably, the width of described gap and described breaking joint is no more than 1.5 millimeters.

Preferably, described tuning circuit include the first inductance, the second inductance and the first electric capacity parallel with one another, can be first Between inductance, the second inductance and the first electric capacity switching and electrically connect with described first earth point first switch and be used for Control the second switch of described second earth point whether ground connection.

The beneficial effects of the utility model are: gap is located close to the bottom margin of metal shell on the back, does not affect metal backing The integrity of shell, and main antenna can be realized by the position of earth point and tuning circuit and cover the requirement of full frequency band.

[accompanying drawing explanation]

Fig. 1 is the front view of this utility model a kind of Whole frequency band antenna structure of mobile phole;

Fig. 2 is the exploded view of Fig. 1 in Whole frequency band antenna structure of mobile phole of the present utility model.

[detailed description of the invention]

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

As depicted in figs. 1 and 2, a kind of Whole frequency band antenna structure of mobile phole 100 includes metal shell on the back 101 and circuit board 105.

Metal shell on the back 101 includes the center 102 of ground connection and as the Department of Radiation 103 of antenna radiator.Center 102 has master The side 102B that body 102A and main body 102A two lateral buckling extend.Department of Radiation 103 be positioned at center 102 bottom and with in The gap 104 of an insulation filling it is provided with between frame 102.And the two ends of Department of Radiation 103 respectively with the end phase of two side 102B To and be spaced arrange formed insulation filling breaking joint 102C.Circuit board 105 is near the limit of the side of Department of Radiation 103 Yu center 102 Edge is concordant so that form clearance zone between circuit board 105 and Department of Radiation 103.Gap 104 connects with breaking joint 102C, its Width should be less than 1.5mm as far as possible.And gap 104 and breaking joint 102C are all filled with by insulant.Due near gold The bottom belonging to shell on the back 101 is arranged, thus without the globality destroying metal shell on the back 101.

Whole frequency band antenna structure of mobile phole 100 also includes distributing point 106 and at least one ground connection being located on Department of Radiation 103 Point.Distributing point 106 is arranged near breaking joint 102C.In this utility model, earth point includes first that distance distributing point 106 is nearer Earth point 107, distance distributing point 106 the second earth point 108 farther out and be positioned at the first earth point 107 and the second earth point The 3rd earth point 109 between 108.First earth point 107 and the second earth point 108 are positioned at the same side of distributing point 106.Circuit Distributing point 106 on Department of Radiation 103 is directly fed by plate 105 by a conductor.First earth point the 107, second earth point 108 with And the 3rd earth point 109 all directly electrically connected with the center 102 of ground connection by conductor.

Additionally, Whole frequency band antenna structure of mobile phole 100 also includes tuning circuit.Tuning circuit includes the first electricity parallel with one another Sense and the second inductance, can switch between the first inductance and the second inductance first switch S1.This first switch S1 can control the Whether one inductance and the second inductance and the first earth point 107 electrically connect.Tuning circuit also includes the first electric capacity and controls first The second switch S2 whether electric capacity and the second earth point 108 electrically connect.In this utility model, the first inductance value is 22nH, the Two inductance value are 9nH, and the first capacitance is 1.5pF.
